Dorothy Shay

Dorothy Shay was an American popular comedic recording artist in the late 1940s and early 1950s, who later became a character actress. She was known as the Park Avenue Hillbilly.

Shay was born Dorothy Sims in Jacksonville, Florida. When she began her career as a straight singer, she took vocal lessons to lose her Southern accent. She sang for the USO during World War II. Dorothy changed her name to Shay in order to not be confused with Ginny Simms, another performer of the day, choosing Shay to honor her mentor Betty Shay . While performing with Morton Gould and his orchestra, she performed an encore, Uncle Fud, a hayseed novelty number that became very popular and launched her solo singing career.
